About Decision Style Questionnaire
The Decision Style Questionnaire — Preliminary consisted of 84 items to be answered on a 5-point Likert scale. Some of the items came from existing measures, including Mann (1982; 22 items, from the following subscales: Decisional Self-Esteem, Vigilance, Defensive avoidance, Hypervigilance), Schwartz et al., (2002; the 5 item Regret subscale), and Scott and Bruce (1995; 23 items from the Rational, Intuitive, Dependent, Avoidant, Spontaneous).
Other measures were considered but not selected because the items were not published (e.g., Epstein & Meier, 1989; Johnson, Coscarelli, & Johnson, 1983), or due to considerable overlap with the included measures (e.g., Harren, 1978; Nygren, 2000), or due to differences in format (e.g., Bruine de Bruin, Parker, & Fischhoff, 2007; Sjöberg, 2003). Thirty-four other items were written specifically for this study.
Of these, 16 were created to complement content areas covered by subscales from other instruments (e.g., “I weigh the pros and cons of each option before I make a decision.” — to complement the Vigilance subscale). Eighteen items were written to capture new content areas, which were: Perfectionism (e.g., “I’m not satisfied until I find the best possible option.”), Risk-seeking (e.g., “I choose the safest alternative when I make decisions.”), and Indecisiveness (e.g., “I cannot make up my mind when I need to make a decision.”).
The new items were created based on their face validity and theoretical relationship to the construct of interest (e.g., the item “My decisions are spontaneous.” was created to complement the “Spontaneous” subscale). The final set of items thus represented 11 theoretical constructs, one of which targeted respondents’ perceptions of themselves as decision-makers: Decisional self-esteem. The others assessed respondents’ decision styles: Perfectionist, Regretful, Indecisive, Risk-seeking, Vigilant, Intuitive, Dependent, Avoidant, Spontaneous, and Anxious.
